Yes. It's a crock. And breaking user binaries from a previous release
(which is hwat happens if you remove ld.so from a pmax 1.3 elf system,
which has user-compiled binaries that refer to ld.so, not ld.elf_so)
isn't really on, is it?

Only the major version is signficant; the minor version is -not used-
at runtime. So if everything is in /usr, then either all programs get
the `old' libc (which breaks programs which make new syscalls) or they
get the `new' libc (which breaks programs that relied on bugs in the
old libc, or rely on behaviour that's changed).
Installing _any_ libraries with $PKGBASE=/usr will break something--
unless we bump library major numbers across releases. Which we don't.
I dont see how that fits, at all, with using $PKGBASE=/usr here.
